dose-finding, safety and efficacy study of rx-0201 plus everolimus in metastatic renal cell cancer

Conditions: Metastatic Renal Cell Cancer

Summary: the purpose of this study is to determine the maximum tolerated dose of rx-0201, up to a target dose of 250 mg/m\^2/day, when given in combination with everolimus (stage 1), and to assess the safety and efficacy of rx-0201 plus everolimus, in subjects with metastatic renal cell cancer (stage 2).

this multi-center, open-label, randomized, parallel group study of rx-0201 in combination with everolimus, versus everolimus alone to treat subjects with advanced renal cell carcinoma will be conducted in 2 stages. stage 1 will be an open-label, dose-escalation study of rx-0201 to identify a safe and tolerable dose of rx-0201 up to a target dose of 250 mg/m\^2/day when given in combination with everolimus. stage 2 will be a randomized, open-label, 2-arm study of rx-0201 in combination with everolimus versus everolimus alone. subjects will receive rx-0201, at the dose identified in stage 1, in combination with everolimus or everolimus alone, for up to 8 cycles to determine safety and efficacy of the combination.
